Abstract
The present invention can realize better cutting performance while suppressing an influence of, for instance, deflection of a head and an increase in a moment acting on a fastening mechanism even when a cutting insert of a long total length is used. A shank of a head replaceable type cutting tool includes: a fastening mechanism that is formed at a leading end part in a longitudinal direction of the shank, and attaches a head; and a recessed part that is formed at the leading end part so as to accommodate a part of a cutting insert held by the head and avoid an interference with the cutting insert. The recessed part may be provided to accommodate a non-use part of the cutting insert held by the head in a state where the head is attached to the leading end part, and avoid an interference with the cutting insert.
